Indicator LED details
The color and action of the indicator LED depends on whether you are connected by USB 3.0 or USB 2.0. For
maximum performance, always use a USB 3.0 port and the included USB 3.0 cable. Note that frame capture
rate will be reduced when connected via USB 2.0.
From the operating system's UVCdrivers, the application will receive the AV.io HD supported color space,
resolution and frame rates. If you’re not sure if your controller is USB 3.0 or USB 2.0, plug AV.io HD into the
capture computer and look at the indicator LED. After initial boot up (red LED), blue is used for USB 3.0 and
green is used for USB 2.0:
Blue LED means USB 3.0
Green LED means USB 2.0
